How We Source Information
Primary sources are required for every factual claim published on this site. Secondary sources — news articles, blog posts, or third-party summaries — are not used as the basis for numeric claims. The following source families are used:
- IRS publications, including Pub. 527 (Residential Rental Property), Pub. 535 (Business Expenses), and Pub. 946 (How to Depreciate Property), as well as IRS Revenue Procedures and Notices.
- Statutory text of relevant legislation, including the One Big Beautiful Bill Act of 2026 and the Internal Revenue Code.
- U.S. Treasury and Department of Labor guidance, including final and proposed regulations, technical corrections, and agency announcements.
- HUD materials for fair housing and landlord-tenant guidance at the federal level.
- State revenue and housing authorities for state-specific landlord-tenant law, including the Minnesota Department of Revenue and Minnesota Housing.
- Bureau of Labor Statistics data for wage, inflation, and labor market figures used in calculator benchmarks.
When a primary source is updated, the relevant articles and calculator documentation are flagged for review within the cadence described in the next section.
04
How We Review and Update Content
Content is reviewed on a schedule tied to the regulatory calendar of the underlying source material:
| Content Category | Review Cadence |
|---|---|
| IRS-driven figures (standard deduction, SE tax rate, mileage rate) | Annually in Q1, plus immediately on any IRS update |
| OBBBA-related figures (overtime premium deduction, SALT cap) | Whenever Treasury or IRS releases new guidance |
| State landlord-tenant content (Minnesota) | On state legislative session calendar (annually, typically May–June) |
| Calculator formulas | Any time an input source changes; verified against primary source before each major deployment |
| General informational articles | Annually, or when a material change in the underlying law or data is identified |
Every article carries both a Published date and a Last reviewed date. Material changes are logged in a per-article changelog. When a figure is updated, the "Last reviewed" date is updated and the change is recorded in the changelog.
05

Not Professional Advice
Important: This site does not provide professional advice.
Nothing on Solo Landlord Tools constitutes tax, legal, accounting, financial, or investment advice. No attorney-client, CPA-client, or fiduciary relationship is created by reading, using, or relying on any content or calculator on this site. Calculator results are estimates based on user-supplied inputs and carry no warranty of accuracy or completeness. Readers should consult a licensed professional before acting on any information published here.
For qualified tax help, the IRS maintains a Directory of Federal Tax Return Preparers searchable by credential and location. For legal questions, most state bar associations operate a referral service; the American Bar Association's lawyer finder links to each state's service.

How We Make Money
Solo Landlord Tools is a free resource supported by two revenue streams:
- Display advertising through Google AdSense (publisher ID: ca-pub-5598653357914791). Google places ads on this site based on page content and, where consent is given, visitor interest. Ad revenue helps cover the cost of maintaining and updating the site.
- The optional Pro tier, which offers saved calculations and PDF export for a monthly subscription fee. The Pro product is entirely optional; all calculators and articles are free without an account.
This site does not currently use affiliate links. If affiliate links are added in the future, they will be disclosed in a dedicated /affiliate-disclosure page and labeled inline.
Editorial firewall: Advertisers and the Pro product do not influence which topics are covered, how figures are reported, or which primary sources are cited. Editorial decisions are made independently by the Kaybi Enterprises editorial team.

Use of AI Tools
Kaybi Enterprises uses AI writing tools to assist in drafting article content and editorial documentation. AI tools are used for drafting, structural outlining, and editing assistance only.
Every AI-assisted draft is reviewed and fact-checked by a human editor against the primary sources listed in the Sources section before publication. AI is not used to generate numeric tax, legal, or financial figures without human verification against a named primary source. If a figure appears in an article, it has been confirmed against the primary source cited.
AI tools are not used to make editorial decisions about which topics to cover, which sources to cite, or how to characterize the state of the law.
